=head2 Default Makefile Behaviour
make config # to check if the Makefile is up-to-date
make clean # delete local temporary files (Makefile gets renamed)
make realclean # delete all derived files (including installed files)
- make distclean # produce a gzipped file ready for shipping
+ make dist # produce a gzipped file ready for shipping
The macros in the produced Makefile may be overridden on the command
line to the make call as in the following example:
=cut
sub check_hints {
- # We allow extension-specific hints files. If we find one we act as if Config.pm
- # had read the contents
+ # We allow extension-specific hints files.
# First we look for the best hintsfile we have
my(@goodhints);
closedir DIR;
return unless @goodhints; # There was no hintsfile
# the last one in lexical ordering is our choice:
- $hint=(reverse sort @goodhints)[0];
+ $hint=(sort @goodhints)[-1];
# execute the hintsfile:
open HINTS, "hints/$hint.pl";
@goodhints = <HINTS>;
close HINTS;
+ print STDOUT "Processing hints file hints/$hint.pl";
eval join('',@goodhints);
+ print STDOUT $@ if $@;
}

Another attempt to fix writedoc() from Dean Roehrich.
+
+v4.092 April 11 1994 by Andreas Koenig
+
+Fixed a docu bug in hint file description. Added printing of a warning
+from eval in the hintfile section if the eval has errors. Moved
+check_hints() into the WriteMakefile() subroutine to avoid evaling
+hintsfiles for other uses of the module (mkbootstrap, mksymlists).
+
+Eliminated csh globbing to work around buggy Linux csh.
+
+In extliblist() libfoo.so.10 now wins against libfoo.so.9.
+
+Use $(CC) instead of $Config{'cc'} everywhere to allow overriding
+according to a patch by Dean Roehrich.
+
+Introduce a ./extralibs.ld file that contains the contents of all
+relevant extralibs.ld files for a static build to shorten the command
+line for the linking of a new static perl.
+
+Minor cosmetics.
+
+v4.093 April 12 1994 by Andy Dougherty
+
+Rename distclean target to plain dist. Insert a dummy distclean
+target that's the same as realclean. This is more consistent with the
+main perl makefile.
+
+Fix up extliblist() so even bizarre names like libfoo.so.10.0.1
+are handled.
+
+Include Tim's suggestions about $verbose and more careful substitution
+of $(CC) for $Config{'cc'}.
+
+Minor cosmetic fixes for my 80-character wide terminal.
+
=head1 NOTES
MakeMaker development work still to be done:
Add a html: target when there has been found a general solution to
installing html files.
+Add an uninstall target.
+
+Add a FLAVOR variable that makes it easier to build debugging,
+embedded or multiplicity perls.
